Hotel employees help with Pittsburgh Marathon security

The Greater Pittsburgh Hotel Association has held a security briefings for the Pittsburgh Marathon every year for the past decade. But, in the wake of the Boston Marathon bombings, the crowd was larger and more attentive.

Bob Winters is Protective Security Advisor for the Department of Homeland Security. He showed a number of videos that showed the employees how they can be more aware of suspicious behavior.

The protocol is called "See Something - Say Something - Do Something." It encourages employees to question behaviors, such as customers who refuse to pay in anything but cash.

And the manager of the Doubletree Hotel, Michael O'Donahue, says he has already noticed an intensified vigilance with his employees since the Boston bombings.

"Believe it or not, we have had a number of backpacks and luggage left around in the lobby by guests going to get a cup of coffee. Employees are pointing these things out more than ever before," O'Donahue said.

Charlie Morton pitched five-hit ball for seven innings, Neil Walker hit a review-aided home run and the Pittsburgh Pirates beat the Cincinnati Reds 3-0 Sunday in a testy game in which benches cleared after All-Stars Andrew Mcutchen and Brandon Phillips were hit by pitches.

The Obama administration will unveil a major climate change plan Monday aimed at a large reduction in greenhouse gas emissions from the nation's coal-burning power plants, a senior administration official told CNN.
